DAmodel: Hierarchical Bayesian Modelling of DA White Dwarfs for Spectrophotometric Calibration
Benjamin M. Boyd, Gautham Narayan, Kaisey S. Mandel +17
We use hierarchical Bayesian modelling to calibrate a network of 32 all-sky faint DA white dwarf (DA WD) spectrophotometric standards () alongside three CALSPEC st…
Faint white dwarf flux standards: data and models
Ralph C. Bohlin, Susana Deustua, Gautham Narayan +7
Fainter standard stars are essential for the calibration of larger telescopes. This work adds to the CALSPEC (calibration spectra) database 19 faint white dwarfs (WDs) with all-sky…
HST/JWST Long-Term Monitoring Working Group Final Report
Saurabh W. Jha, Dana I. Casetti-Dinescu, Gary M. Bernstein +9
The Astro2020 Decadal Survey recognizes time-domain astronomy as a key science area over the next decade and beyond. With over 30 years of HST data and the potential for 20 years o…
Windows on the Universe: Establishing the Infrastructure for a Collaborative Multi-messenger Ecosystem
The 2023 Windows on the Universe Workshop White Paper Working Group, T. Ahumada, J. E. Andrews +43
In this White Paper, we present recommendations for the scientific community and funding agencies to foster the infrastructure for a collaborative multi-messenger and time-domain a…
SpectAcLE: An Improved Method for Modeling Light Echo Spectra
Roee Partoush, Armin Rest, Jacob E. Jencson +17
Light echoes give us a unique perspective on the nature of supernovae and non-terminal stellar explosions. Spectroscopy of light echoes can reveal details on the kinematics of the…
NIRCam Performance on JWST In Flight
Marcia J. Rieke, Douglas M. Kelly, Karl Misselt +7
The Near Infrared Camera for the James Webb Space Telescope is delivering the imagery that astronomers have hoped for ever since JWST was proposed back in the 1990s. In the Commiss…
